Well, you certainly *can* draw to them in sequence. Perhaps it's a case of 'you shouldn't do that'. If I'm drawing to multiple attachments simultaneously then that makes sense. But I can set the draw...

It is my understanding that nVidia's CSAA offers some memory savings over MSAA (over both renderbuffers and textures). I don't know if this information is out of date (or wrong), but if true, this is...

One more thing. Wouldn't there be less memory overhead in using multisampled textures? In order to blit, I need a multisampled render buffer (which I draw to) and an additional texture allocation for...

Because I mistakenly believed that a blit was a simple memcpy. After some digging, I realized it isn't. I did end up just doing the timings and got nearly identical results both ways (which supports...
